Another object of the invention is to provide a bail shape member adjustably con nected with the sides of the seat, which memably connected to the sides of the seat to support a back-rest, a portion of said ball being so disposed with respect to the backrest. as to prevent its accidental engagement with an associated article of furniture so as to damage the same in the moving about of the chair, to which it is subjected in use.

These objects of the invention as Well as others, together with the many advantages thereof will more fully appear as I proceed V a metallic strap :18. The end portions of said with my specification.

In the drawings Fig. l is a perspective view of the seat and back-rest supporting structua'e of a chair em- 3o bodying my invention.

Fig. 2 is a view in rear elevation of the same.

Fig. 3 is a view in side elevation of the same.

Referring now in detail to that embodiment of the invention illustrated in the drawings, 1 indicates as a whole the seat of a chair mounted for operative connection with a base (not shown), in any suitable manner. Said 4!) seat as shown herein is substantially rectangular and is provided at each side with a flange or strip 3 provided at its front end with longitudinally spaced openings 4.

55 indicate'supporting arms for a backrest 6. Said arms are made of flat strip stock and in the bottom end of each arm are longitudinally spaced openings 7 through any one of which a screw 8 may be inserted and then screw threaded into a suitable opening prou0 vided therefor in the associated strip 3,

'whereby the arms may be adjusted with respect to the seat 1. V The top end of each arm is curved inward as at 9 and terminates'in a short upright extension'lO, the purpose of Y which will soon appear.

11 indicates as a whole an inverted U or bail shaped member that cooperates with the arms 5-5 to support the back rest 6. Said member which is preferably made of tubular stock includes, side-members 1212 and a top cross member 13, connected thereto by .rounded corners 1414: Substantially the 7 bottom half of each side member is bent out of the plane of the top half and thebottom end extremity of each sidemember is adjustably and pivotally connected .to the associated flange or strip 3 in th thereof by a screw 15.

On the inner face of each side member 12 near the curved portion that connects the top and bottom portions thereof, is fixed in any e desired opening 4 suitable manner, afi inwardly extending bracket 16 that terminates in. an upright ex- On the rear side of the back-restG is fixed strap extend beyond the ends of said back rest and are bent to form rearwardly extending ears 1919. Each ear 19hr the back rest is engaged between the'extension 10 and '17 respectively of associatedarmsb and bail members 12 respectively to bese'cured thereto .by bolts. or rivets 20. In this respect it is theback rest, it being impossible for the back rest to swing downwardly about the pivots 2O beyond'that point wherein the bottom 1 edges of the ears l9. engage the curved portions 9 o fthe back-rest arms.

To adjust the back-rest the 'screws8 are removed and the, arms 55 are .adjusted'vertically (up orldown) and the screws 8 are" then replaced in the proper holes 7 and the associated holes in the rear ends of the strips 3. The screws 15 are then removed and the bottom ends of the members 12 are moved forwardly or rearwardly and the screws 15 chair about from one point of use to another,v

but it also prevents the engagement of the side of the backrest with any associated article of furniture with resulting damage v thereto against which the chair may be accidentally moved. Again such a bai-l having its side members connected by an integral cross member at the top, actsto more rigidly hold the back-rest structure against'la-teral shifting with attending racking.

While in describing the invention, I have referred indetail to the form, arrangement and construction of'the par-cs thereof, the same is to be considered as illustrative only, so that I do not Wish to be limited thereto except as may be specifically set forth in the appended claims.

I claim as my invention 1., A chair embodying therein a seat, supporting arms pivotally and vertically adjusably connected to the seat, a bail lncluding side arms and a top connecting member, said side arms being adj ustably connected to said seat, inwardly extending brackets on the side members of the bail, a back-rest and means connecting said back-rest to said supporting arms and to said brackets in a plane below the top connecting member of said bail;

2. A chair embodyihg therein a seat, supporting arms pivotally and vertically adjustably connected at their bottom ends to said seat, a bail including side arms and atop connecting member, said side arms being adjustably connected to said seat, inwardly extending brackets on said side arms of the bail and including portions disposed adjacent the top ends of said supporting arms, a back-rest and means pivotally connecting said backrest with said top ends of said arms and said portions of said brackets so that said backrest is supported thereby.

3. A chair embodying therein a seat, sup porting members operatively connected at their bottom ends to said seat, a bail includseat, connecting means between the top ends of the supporting arms and side members of the bail, said connecting means extending forwardly of the sides of the bail, and a back rest pivoted to the connecting means forwardly of the sides of the bail and located below the top connecting member of the bail.

ing side arms and a top connecting member, s

means connecting said arms with said seat, brackets extending inwardly from said side arms towards the top ends of said supporting members, a back-rest and means connecting said back-restto said supporting mem bers and brackets respectively at a point be low said top connecting member.

4;. A chair embodying therein a seat, supporting arms pivotally and vertically adjustably connected to the seat, a bail including side arms and a top connecting member, said side arms being adjustably connected to-the
